Testagen 20mg
Testagen (Lys-Glu-Asp-Gly) is a synthetic tetrapeptide bioregulator studied for nuclear DNA-binding activity and pituitary-thyroid axis effects in animal models. Fedoreyeva et al. (Biochemistry (Moscow), 2011; PMID 22117547) documented its penetration into the cell nucleus and sequence-specific interaction with DNA in HeLa cell culture. For Research Use Only. Not for human consumption.

Description
About this peptide
About This Compound
Testagen (Lys-Glu-Asp-Gly) is a short synthetic peptide belonging to a family of tetrapeptide bioregulators derived from tissue-specific amino acid composition studies. It has been examined in cell-culture and animal-model research for its capacity to enter the cell nucleus and interact with defined DNA sequence motifs, as well as for its activity within the pituitary-thyroid axis following hypophysectomy in avian models. The way a key is cut to fit one specific lock, Testagen and related short peptides are studied for sequence-specific binding to particular regions of genomic DNA.
Research Context
Fedoreyeva et al. (Biochemistry (Moscow), 2011; PMID 22117547) documented Testagen's penetration into the nucleus of HeLa cells and its sequence-specific interaction with deoxyribooligonucleotides, noting a binding preference for CAG-containing DNA sequences. Kuznik et al. (Bulletin of Experimental Biology and Medicine, 2008; PMID 19024016) studied Testagen alongside a related tetrapeptide in neonatally hypophysectomized chickens, documenting changes in thyrotropic and thyroid hormone concentrations and thyroid gland structure over a 40-day observation period. Kuznik et al. (Advances in Gerontology, 2011; PMID 21809626) extended this hypophysectomized bird model to mature and old animals, comparing thyroid morphology and hormonal activity outcomes across age groups.

We independently test selected batches and publish those reports. Not every batch has one, and this strength and origin does not have a published report right now. You can read how certificates of analysis work, or browse every report we have published.
Shipping & Storage
Handling this material
Shipping
Orders ship within 24 hours. Delivered via USPS Priority or standard FedEx unless expedited shipping is selected at checkout. Tracking is emailed on dispatch and mirrored in your account.
In-transit handling
Lyophilized vials are shelf-stable and ship at ambient temperature. Storage in our warehouse is cooled; shipment does not require refrigeration.
Long-term storage
Lyophilized vials are shelf-stable at ambient temperature; refrigeration (2–8°C) extends shelf life. Where a published Certificate of Analysis exists for your strength and origin, it is on the COA tab. Not for human or animal consumption.
Returns
Because these are research-grade biologics, we cannot accept returns on opened vials. Damaged-in-transit shipments are replaced at no cost within 7 days of delivery.
Frequently asked
Common questions
No. Every SKU is labeled and sold strictly for laboratory research use only. These are not drugs, dietary supplements, or veterinary products. Research Use Only policy
We independently test selected batches at a third-party lab and publish those certificates of analysis. Not every batch has one. The COA tab on each product shows whether the strength and origin you picked has a published report.
Discreet outer box, no branding on the exterior. Invoices are emailed rather than enclosed. Lyophilized vials are shelf-stable and ship at ambient temperature; no cold-chain packaging is used in transit.
All in-stock items ordered on the same day ship together. Backorders release automatically once the missing SKU is back in stock.
